Contrary
to evolutionist claims, mammals emerged on Earth suddenly without
any predecessors. Moreover, evolutionists have no explanation for
the origin of distinct mammal groups.

As so far examined, the theory of evolution proposes
that some imaginary creatures that came out of the sea transformed
themselves into reptiles and that birds were formed by the evolution
as that of reptiles. According to the same scenario, reptiles are
the ancestors not only of birds but also of mammals. However, on
the one hand, there are big, structural gaps between reptiles, which
have scales on their bodies, which are cold-blooded, and which reproduce
by laying eggs, and on the other, mammals, which have fur on their
bodies, which are warm-blooded, and which reproduce by giving birth
to live offspring.

SEA MAMMALS AND BEARS

Sea mammals, such as dolphins and whales, are the primary
animals that put evolutionists into a quandary. According
to evolution, these animals ought to have evolved from land
mammals, but there is no land animal that can be considered
the "ancestor" of these species. In his book The Origin
of Species, Darwin asserted that "whales had evolved from
bears that tried to swim." Later, however, he realized the
unreasonableness of this claim and omitted this subject
from the latest edition of his book.

An example of the structural barriers between
reptiles and mammals is their jaw structure. Mammals' mandibles
consist of only one mandibular bone and the teeth are placed on
this bone. In reptiles, however, there are three little bones on
both sides of the mandible.

THE FOSSIL EVIDENCE

There is no difference between mammal fossils dozens
of millions of years old and the mammals living today. Furthermore,
these fossils emerge suddenly, with no connection to any
species that had gone before.

Another basic difference is that all mammals
have three bones in their middle ear (hammer, anvil, and stirrup).
In all reptiles, there is a single bone in the middle ear. Evolutionists
claim that the reptile jaw and reptile middle ear evolved gradually
into the mammal jaw and ear. Yet the question of how this change
occurred remains unanswered. In particular, the question of how
an ear with a single bone evolved into an ear with three bones and
how the process of hearing kept on functioning in the meanwhile
can never be explained.

THE PROBLEM OF FURS

The bodies of mammals are covered by furs or hairs,
which is a characteristic that is not found in any other
living group. The bodies of reptiles, the alleged ancestors
of mammals, however, are covered with scales. Evolutionists
prefer to keep silent in response to the question of how
scales have been transformed into mammal furs.

Not surprisingly, not a single fossil to link
reptiles and mammals is to be found. This is why evolutionist paleontologist
Roger Lewin was forced to say that "the transition to the first
mammal... is still an enigma".43

George Gaylord Simpson, one of the biggest evolutionary
authorities in the 20th century makes the following comment on this
fact that is quite perplexing for evolutionists:

The most puzzling event in the history of life
on earth is the change from the Mesozoic, the Age of Reptile, to
the Age of Mammals. It is as if the curtain were rung down suddenly
on the stage where all the leading roles were taken by reptiles,
especially dinosaurs, in great numbers and bewildering variety,
and rose again immediately to reveal the same setting but an entirely
new cast, a cast in which the dinosaurs do not appear at all, other
reptiles are supernumeraries, and all the leading parts are played
by mammals of sorts barely hinted at in the preceding acts.44

BATS AND THE SONAR SYTEM

Bats, the only flying mammal species, are one of the
organisms that challenge evolution. Evolutionists assert
that bats evolved step by step, but they have no consistent
answer about the origin of their wings. Moreover, bat fossils
aged 50 million years demonstrate that these animals came
into being in their present state. Moreover, bats have a
very sensitive sonar system. With their large ears, they
sense and analyze the echo of the high-pitched sounds they
emit. The emergence of such a complex system cannot be attributed
to chance.

All of these demonstrate that mammals also appeared
on Earth suddenly and fully formed, without any ancestors. This
is concrete evidence of the fact that they were created by God.
